This invention aims to provide novel means whereby cold air may be drawnfrom a point adjacent to the floor of a room, and be heated, theconstruction being such that the heating {if is brought about throughthe instrumentality of the products of combustion passing up a stovepipe, and no additional expenditure of fuel being necessary, in order toheat the air as aforesaid.

It is within the province of the disclosure to improve generally and toenhance the utility of devices of that type to which the inventionappertains.

WVith the above and other objects in View which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, may be made within thescope of what is claimed, without departing from the spirit of theinvention.

In the drawings Figure 1 shows in longitudinal section, a deviceconstructed in accordance with the invention, parts being broken away;

Figure 2 is a longitudinal section taken in a plane at right angles tothe cutting plane in Figure 1;

Figure 3 is a horizontal section; and

Figure 4 is a sectional elevation showing the means whereby rotation isimparted to the damper.

Figure 5 is a central vertical sectional view of a modified form of theinvention.

In the accompanying drawings, the numeral 1 indicates a barrel-shapedbody, adapted to be connected at its ends with a stove pipe 2 or othermember through which the products of combustion pass, from a stove orfurnace. Located within the body 1 and extended transversely of thesame, is a flue 3 which, preferably, is of greatest diameter from apoint intermediate its ends, the flue 3 tapering to its ends 4 and 5,the ends 4 and 5 being of cylindrical form, and being mounted to turn inthe body 1. In order that the flue 3 may be held against moving endwise,as it turns, the ends 4 and 5 of the flue are supplied with flanges 6which engage the inner surface of the body 1 as clearly shown in thedrawings. The body 1 preferably is made of separable parts, as indicatedat 7 in Figure 2, the parts 7 being joined together in any suitl5 ableway, as shown at 8. The body 1 is made in separable parts, as aforesaid,so that the flue 3 may be mounted in place readily within the body 1, asshown in Figure 1 of the drawings. A damper 9 is connected to the flue 3and is of such size as to control .the' I passage through the body 1.

The numeral 10 marks a vertical conduit of such length as to extend downto a point adjacent to the floor of the room in which, the device ismounted. The conduit 10 has a '7 horizontal end 11 which is received inthe end 5 of the flue 3. There is a transverse slot 12 in the end 11 ofthe conduit. :On the end 5 of the flue 3 is mounted an operating mem-;ber 14 of any desired sort, such as a wheel 14. A securing element 15connects the wheel 14 with the end 5 of the flue 3. The securing element15 extends into the slot 12 that is formed in the end 11 of the conduit10. I

In practical operation, cold air taken from a point near to the floor,moves upwardly through the conduit 10 and is heated in the flue 3, theheated air passing out through the end i of thefiue and creating anup-draft of, 30 cold air through the conduit 10. The products ofcombustion from a stove, furnace, fire-place or the like, pass upwardlythrough the pipe 2 and the body 1, and, consequently, the air thatpasses through the flue 3 is heat- 35 ed without any additionalexpenditure of fuel. The draft through the body 1 may be regulated byrotating the flue 3, so that the damper 9 stands either open or closedwith regard to the body 1. The slot 12 is 1115390 length. When thesecuring element or screw 15 is at one end of the slot 12, the damper 9is closed, and when the screw or securing element is at the opposite endof the slot 12, the damper is open. The operator simply turns; the handwheel 14 as far as possible, in one direction or in an oppositedirection, and he is assured that the damper is either open or closed,depending upon the position he may. wish it to be. T

The securing element 15 has a number of functions. First, it connectsthe wheel 1 1 to the flue 3, so that when the wheel is turned, the fluewill be turned also, to open or close the damper 9. Second, because thesecuring element 15 is received in the slot 12, the end 11 of: theconduit 10 is held intheend 5 of the flue 3. Third, because the-securingelement or screw 15 engages the part llatthe ends of the slot 12, theoperator can determine definitely the position of the damperS, ashereinbefore explained.

In Figure 5 of the drawings, parts hereinbefore described have beendesignated by numerals previously used, with the suflix a. In this-formof. the invention, the damper: 9 and attendant parts are omitted, andadamper 25 is placed in the pipe 2a, above the flue 3a, the numeral 26designating any. suitable means for manipulating the damper.

hat is claimed is 1'. In a device of'the class described, abody ofgreatest diameter intermediate its ends and:tapered toward its-ends, anda flue eX- tended throughthe bodytransversely and located at the placewhere the body is of greatest diameter, the flue being of greatestdiameter-at a point intermediate its ends and at the-longitudinal axisof the-body, the flue tapering toward its ends within the body.

2. In a device of the classdescribed, a'body of greatest diameterinter-mediate its ends and taperedtoward itsends, and a flue extendedthrough the body transversely and located at the place where the bodyisof greatest diameter, the flue being of greatest diameter at apointintermediate its ends and tapering toward its ends within'the body, theflue being provided with circumferential flanges which-cooperate withoppositely disposed portions of the body.

In testimony that I claim the foregoing as my own, I- have heretoaifixed'my signature.
